Way back in the stone age, I was a sys admin at my university, working
the graveyard (i.e., backup) shift two days a week and an occasional
Sunday. On Sundays, we did the full backup and restore, but we
switched out the disk packs (I said this was a long time ago) so we
never lost more than a week's worth of data at the time. Well, almost
never....
My last Sunday there, I accidentally reinitialized all the disks after
the backup but before I had switched them. Then, I realized what I
did, switched them anyway, and reinitialized them again, then did a
full restore.
Everything would have been fine if the file system hadn't crashed that
Friday afternoon....
This was on a Xerox Sigma 7 (I'm dating myself).
UNIX horror story: 24 years ago, I was working on a development system
(i.e., nothing critical on it) and my latest build didn't work the way
I expected, so I erased it with an 'rm -rf *' - except that I was in
the root directory at the time, not my build directory. By the time I
realized what I had done, it was too far gone to recover, so I wound
up reinstalling the whole system. No harm done (I did things like
that sometimes on purpose, when it was *my* machine involved), but I
don't do 'rm -rf' of anything any more without double-checking where I
am FIRST, even if the default "-v" is set.
(unsigned confession)
